वाटर पोर्टल / वर्षाजल संचयन / भूजल पुनर्भरण
From Akvopedia
भूजल पुनर्भरण प्राकृतिक भूजल आपूर्ति की वृद्धि का तरीका है जो मानव निर्मित तरीकों जैसे घाटियों, खाइयों, बांधों, या इंजेक्शन कुओं के भूजल क्षमता में वृद्धि करता है. एक्वीफर भंडारण और प्राप्ति (एएसआर) भूजल पुनर्भरण की एक विशिष्ट शैली है जिसके जरिये भूजल पुनर्भरण के साथ-साथ भविष्य के उपयोगों के लिए जल संरक्षण भी किया जाता है.
Climate change considerations
- More storage capacity needed to overcome seasonal dry periods and to reduce floods.
- Higher rainfall intensities may exceed infiltration capacities. Create storage, enhanced infiltration or artificial recharge.
- Lower rainfall results in the need for transport and storage of water from other areas.
- Changes in vegetation will cause changes in evapotranspiration, surface runoff, erosion and sediment transport/deposition. This requires water and soil conservation measures, like terracing.
Field experiences
These projects may be utilizing groundwater recharge techniques and are part of the project listing in Really Simple Reporting (RSR) on Akvo.org.
