| Abstract | Interceptor drains are one of the physically feasible drainage alternative to recover s losses from unlined irrigation channels near their vicinity. This study is performed to the interceptor drain design parameters (of installed interceptor), distance of intercepto from canal, depth of interceptor drain below ground level and quantity of water intercer the interceptor drain with groundwater flow model (MODFLOW). The seepage obtaim Model then compared with USBR procedure and Analytical method (by Sharma and C The quality of water intercepted by the interceptor drain is also checked. To evaluate above drain design parameters, three simulations with MODFLOW using evapotranspiration, recharge and river package along with SIP for solution were neede seepage predicted by Model was nearest to the physically measured (inflow-outflo ponding test methods) than USBR procedure and Analytical method. The hy conductance of the interface (CDRN) between the aquifer cell and the drain come~ 0.1099 m2 /day. Different locations of interceptor drain, depth of interceptor drain ground surface from 1.8 to 5.8 meters and distance from canal center line from 23.50 tc meters are studied. For the pipe size and length calculation, the Manning equation mi for non-uniform flow is used. It is concluded that deeper drains yielding more discharge. However also inducerr seepage is higher for deeper drains. Drains located further away from the canal have less intercepted discharge. The water quality of intercepted water remains approximate!. as that of canal water. The water intercepted can be reused for irrigation and it is witl safe limits. |
