Cs. Desilva et Ek. Weatherhead, OPTIMIZING THE DIMENSIONS OF AGROWELLS IN HARD-ROCK AQUIFERS IN SRI-LANKA, Agricultural water management, 33(2-3), 1997, pp. 117-126
A case study was conducted into the use of large diameter wells (agrow
ells) for supplementary irrigation from the hard-rock aquifer in the N
orth-Western province of Sri Lanka, Two existing models, a radial grou
ndwater flow model and a soil water balance, were used together to rep
resent the agrowell irrigation system. A technique is described to opt
imise new agrowell systems by deciding the optimum well radii for give
n aquifer characteristics and well spacings, or to optimise existing a
growell systems by deciding the sustainable irrigable command areas. (
