TL;DR: The concept of dividing streamline is used to quantify the effectiveness of the interceptor ditch for limiting the spread of potential contaminants in shallow aquifers in this article, and the simulation results suggest that the interceptors may create an effective hydraulic barrier to the movement of agricultural contaminants in ground water, but its effectiveness is subject to seasonal changes in hydrological conditions, including the regional water-table gradient, the distribution of recharge and discharge, and the ditch stage.
Abstract: The ground-water pattern in the vicinity of an interceptor ditch used for agricultural drainage is simulated using flow and stream function models to explore the possibility of using interceptor ditches to control the spread of agricultural chemicals in shallow aquifers. The concept of the dividing streamline is used to quantify the effectiveness of the interceptor ditch for limiting the spread of potential contaminants. The simulation results suggest that the interceptor ditch may create an effective hydraulic barrier to the movement of agricultural contaminants in ground water, but its effectiveness is subject to seasonal changes in hydrological conditions, including the regional water-table gradient, the distribution of recharge and discharge, and the ditch stage. A quantitative relationship between effectiveness of the ditch and these hydrological conditions is established.

TL;DR: In this article, the authors analyzed the relationship between the maximum water-table height and discharge rate in terms of the drain spacing, the depth of the permeable substratum, the artesian head and the hydraulic conductivity of the saturated soil.
