description abstract | In Egypt, the government has initiated large-scale projects to
reuse drainage water to face the great challenges due to its limited
water resources. Taking into consideration the environmental aspects
of drainage water reuse, the diffuse pollution of water resources
from agricultural sources (fertilizers) is a major environmental issue.
A high percentage of applied fertilizers is lost because of poor management,
which leads to nutrients leaching through different crop rotations.
An integrated precise tool to predict nitrate leaching is needed for
the adoption of management policies to address water quality problems
and to establish limits for sustainable drainage water reuse. To quantify
and analyze subsurface nitrate leaching, a combination model of the
system was made in DRAINMOD-N software. The study was applied to the
Mashtul Pilot Area, Egypt, as a case study. In addition to analyzing
subsurface nitrate leaching, the model calculated nitrate leaching
for the year 2020 for the area. The modeling system combination was
applied to the study site to model nitrate leaching predictions after
ten years. The system combination consisted of DRAINMOD-N and Geostatistical
Analyst. The study revealed that the modeling system performed well
and was reliable and accurate in predicting nitrate leaching. Therefore,
this system can be used to develop guidelines for drainage design
and water management to control nitrate pollution. The system can
potentially be used by policymakers in the long-term strategic management
of large-scale irrigation development projects. | |
