Potential activity | Observed in the field/reported | Potential impact on the environment |
Water availability in the river and trends | Yes (Observed sharp reduction in seasonal water availability instream for two years for dry and wet seasons). | Very high flows in the rainy season and water not available for flow in the river the dry season only existing in small pools. |
Rainfall run off patterns and nature | Yes (observed higher rainfall-runoff peak for second monitoring season). Reported rainfall increase and higher flow peaks but longer low flow and no flow seasons | High hydrologic response slope curve can mean sharp rainfall-runoff hydrograph curve and dry season low water availability instream. |
Rainfall trends | · Change in timing of rainy season towards start and earlier in the year (October to Deceember) from end-year away from December toJanuary · Increase in length of dry seasons · Increase in amounts for rainfall events · Increase intensity of dry season rain days | Seasonal changes can affect water availability instream |
River flow trends | · Higher river flow peaks · Shorter time of flow seasonal flows · Less sedimentation | High flows in the rainy season observed only for the field data collection time |
