Two geological units are gift inside the Lerma basin. Quaternary glacis composed of layers of gravel with a loamy matrix and of maximum thickness 10 m expand over 34% of its region. Soils with excellent drainage conditions, low salinity and little danger of erosion are discovered on the Quaternary substances, which makes these soils prime for irrigation. The Quaternary glacis overlay Tertiary materials. The Tertiary lutes and marls are interblended with thin limestone and gypsum layers, and generate sluggish-drainage soils of high salinity and steeper slopes, which make these areas much less appropriate for irrigation. The Quaternary materials provide perched aquifers over the lowpermeability Tertiary materials. Those aquifers are recharged via each precipitation and irrigation water, and drained by means of springs which feed a network of gullies. The community of gullies crosses Lerma basin from east-southeast to west-northwest. The low permeability of the Tertiary materials ensures a suitable manage of the water balance.


Agriculture was the main land use in Lerma basin, overlaying 48% of the entire basin area. Major plants were just like those within the middle Ebro Valley: maize (46%), winter cereal (19%), vegetables (15%), sunflowers (9%) and others. Sprinkler irrigation became the primary gadget used, although drip irrigation becomes also present, especially for vegetables. Properly-nice irrigation water came from reservoirs positioned in a neighboring basin which are fed with water from the Pyrenees Mountains (northeast Spain). The trend outcomes beneath exclusive situations are supplied. For non-irrigated conditions, reducing developments have been detected for Q, SL and NL. No trends were detected in the water quality parameters. Traits in the non-irrigated duration are associated with the lower in precipitation between 2004 (634 mm) and 2005 (237 mm), as trends were detected in parameters influenced by this variable, i.e. drift, salts load and nitrogen load. The trend in go with the flow in the course of the irrigated duration changed into 3.eight L s-1 12 months-1, but essential differences have been discovered between the transformation and the consolidation periods, 2.1 and –5.8 L s-1 12 months-1, respectively. The sudden growth in drift located among 2008 and 2009 is accountable for this unusual trend sample. A distinctive behavior became determined between EC and NO3– all through the irrigation period, when developments had been assessed for the exceptional degrees of irrigation implementation. Each EC and NO3– expanded in the course of the transition period; but, EC reduced at some point of the consolidation duration at the same time as NO3– remained strong. The EC sample can be defined through both a dilution impact and soil salt leaching due to irrigation water entering the device. For the first years, EC accelerated as soluble salts stored in soils and geological substances had been leached. After the successive washing out of those salts, EC is now reducing and is anticipated to lower till a new equilibrium in salinization procedures is reached. according to, the time that elapses till new equilibrium states are reached in salt balances varies from much less than a year (root area) to lots of years (nearby basin), and could depend on climate. After reviewing numerous modeling studies, advocate that the time required for a small arid basin to reach a new equilibrium in its salt balance is among one hundred and a thousand years. Nitrate concentration styles can be explained with the aid of the multiplied use of fertilizers while the irrigation vicinity and extent had been growing, as no fertilizer turned into carried out during 2004-2005. Proceeding to our tracking of Lerma gully, using fertilizers in rained agriculture was a not unusual practice, but changed into interrupted for more than one years when work for transformation to irrigation commenced. The previous fertilization and climatic situations provide an explanation for the high nitrate values obtained all through the non-irrigated length that is comparable to the ones of the irrigated period, in particular in the dry 12 months 2005. High nitrate concentrations have also been pronounced for dry years by Reynolds and Edwards for upland streams and long-time period nitrate awareness time collection, respectively. By way of 2006, maximum of the nitrate stored in the soils and aquifer for the duration of rained situations should were launched. At this second, who coincides with the start of irrigation, minimum values in nitrate concentration have been recorded. The revolutionary increase in fertilizer utility coupled with irrigation extended the nitrate attention inside the gully. After enlargement of irrigation, the amounts of water and fertilizer carried out have become stable; the hydrological machine appears to have reached a new equilibrium regarding nitrate concentration, although it affords a degree of variant because of the seasonality in irrigation, fertilization and weather. As a result, nitrogen dynamics appear to have a put off in reaction to input changes at the upper basin scale. This is probably due to water-transit instances in soils and groundwater. This postpone is, as anticipated; decrease than what become determined at local basin scales, in which delays can attain greater than 10 years.


The aforementioned approaches affecting go with the flow, salinity and nitrate concentration have results for the exported loads of contaminants. Each SL and NL increased at some stage in transition after which decreased during consolidation. However, SL decrease in the course of consolidation was enormously higher than that of NL. at the same time as SL reduced due to each lower go with the flow and EC, NL turned into most effective stricken by the decrease go with the flow, as NO3- remained stable for the duration of the consolidation period.

The hydrological dynamics of the Lerma basin were altered with the aid of the incorporation of irrigation return flows. Even though rain occasions imposed top notch variability at the hydrological reaction, the effect of irrigation may be remote to an affordable diploma with the aid of the usage of non-parametric records. No large relationships were discovered between precipitation and different hydrological variables of interest. But, great relationships have been found between irrigation volumes and drift and exported hundreds of salt and nitrate, highlighting irrigation as a controlling component of the located modifications. Implementation of irrigation imposed big traits on hydrological variables: (a) increase in waft at Lerma gully, detected both monthly and yearly; (b) decrease in salinity and boom of nitrate concentration, especially in summer season months; and (c) growth in exported loads of salts and nitrate, because of the boom in waft. The detected tendencies in Q and EC had been as an alternative one of a kind to the ones reported in the literature for different irrigation basins, in which different techniques or land makes use of interacted with the effects of irrigation. The NO3-trend was steady with that detected at better scales however with lowering values downstream, because the effect of other land makes use of received relative importance for water first-class. Changes in float especially managed the exported mass of pollution. It is essential to maintain amassing facts inside the have a look at location so that you can assess the medium- to long-term implications of irrigation implementation.

The results of this have a look at have shown the hydrological adjustments imposed on a flow as a consequence of the implementation of irrigation in its hydrological basin. The data set generated can also be used for trying out hydrological fashions that simulate the influences of land-use changes, along with implementation of irrigation. Those impacts rely on the characteristics of the irrigation undertaking, the hydrology of the basin and the irrigation and fertilization management, among other elements, which should be taken into consideration in order to reap the adequate control of water assets.
