**6. Direct surface techniques**

This method of groundwater recharge is very simple and most widely used. Under this method stored surface water is directly conveys into an aquifer without infiltration and water percolates naturally through the unsaturated zones of soil profile and join the groundwater table.

### **6.1 Flooding/water spreading**

This is a very common method of groundwater recharge (**Figure 1**) [8]. This is
