|text1='''Effects of drought''': Less water stored behind dam. <br>'''Underlying causes of effects''': Less recharge. <br>'''To increase resiliency of WASH system''': Reduce water loss behind by using adjustable sheets filled with small size gravel on the upstream side of the dam.
|heading2=Drought effects on cement
|text2='''Effects of drought''': Badly made concrete and cracked linings (e.g. in tanks, dams, waterways, wells, and other structures). <br>'''Underlying causes of effects''': Less water used for curing; Impure water used for mixing. <br>'''To increase resiliency of WASH system''': Ensure adequate mixing, ratios, purity of ingredients; Minimize water content in mixture; Ensure adequate curing.
|heading3= Floods
|text3= Leaky dams are meant to handle flash flood rain events. Very intense rain events could provide faster erosion or carry sediment loads beyond the dam (contrary to the dam's purpose of filtering silt). Or if the rain is slow and long, greater water amounts could add greater silt behind the dam in a shorter amount of time, which may clog the ability of the dam to do direct groundwater recharge. In these cases, more attentive maintenance is required to check for erosion and silt build ups (or escapes).
