GULLY PLUGGING SPILLWAY IS AN EFFECTIVE GULLY REHABILITATION MEASURE: A CASE STUDY OF DISTRICT GUJRAT-PAKISTAN

Abstract

Soil erosion is the universal land degradation event which invites an enormous challenge for its rehabilitation. Among all forms, gully erosion is the most worst and visible form of water erosion which cannot be controlled without any permanent gully stabilization structure. Therefore, the study was conducted to evaluate the impact of gully plugging spillway to rehabilitate the eroded land. For this purpose, a highly eroded site was selected within the study area, surveyed to estimate the structural design and brick masonry work was executed accordingly. The consequences of study clearly illustrated that straight drop spillway is an effective hydraulic structure which considerably fulfilled its objectives by plugging the gully to stop further erosion as well as stabilizing the eroded land.
