The document discusses restoration efforts along the Truckee River, which flows from the alpine Lake Tahoe region to the desert basin. It has undergone extensive habitat degradation and watershed impacts over the last century. Restoration projects use various techniques like wetland and stream restoration to improve habitat, reduce flooding, and enhance water quality. They involve partnerships across many agencies and non-profits to restore the river corridor from its headwaters to mouth.
Overview of small tank cascades: Evolution, present status and future scenariosDr. P.B.Dharmasena
Presentation made at Policy Dialogue on Restoration and Management of
Small Tank Cascade Systems on 14 February, 2017 at
Bandaranaike Centre for International Studies (BCIS), Colombo
This slide show depicts how rainwater harvesting has been accommodated in policy and legislation in India and specifically in the state of Karnataka. It gives example of projects in rural areas and in the city of Bangalore.

GROUND WATER RECHARGE TECHNIQUES BY CH.APPARAO (Research Associate, ARS, ATP)Apparao Chodisetti
Ground water recharge is the process whereby the amount of water present in or flowing through the interstices of the sub-soil increases by natural or artificial means. Rainfall is the principal source for replenishment of recharge of ground water. Other sources include recharge from rivers, streams, irrigation water etc. An unconfined aquifer is recharged directly by local rainfall, rivers, and lakes, and the rate of recharge will be influenced by the permeability of overlying rocks and soils. A confined aquifer, on the other hand, is characterized by an overlying bed that is impermeable, and local rainfall does not influence the aquifer. It is normally recharged from lakes, rivers, and rainfall that may occur at distances ranging from a few kilometers to thousands of kilometers.
Paul Roebuck, one of our London based ecologists, takes you through some basics on green infrastructure in the UK and highlights some really interesting projects we have worked on and exciting future developments.
The slides cover legislation, mitigation, habitat creation, ecology impact assessments and green roofs and walls.

Modifying River-Floodplain Systems: A Historical and Ecological PerspectiveNoam Ross

Jennifer Birchfield, Water Program Director with Save the Dunes, will update the group on several news items and initiatives.
Save the Dunes in partnership with the city of Valparaiso, was recently awarded a $607,000 EPA grant to improve a large detention area located at Evans & Roosevelt in Valparaiso. The basin feeds into the Salt Creek watershed and eventually into Lake Michigan.
Birchfield said more than 500 acres of developed land drains into the 2-acre Thorgren basin after a storm. That water contains pollutants, such as lawn chemicals, oil and animal feces. The grant money will spur efforts to naturalize the basin to mimic a wetland surrounding to filter pollutants. Concrete will be replaced by a meandering waterway. Turfgrass will be replaced with native plantings that have deep roots that absorb water and pollutants.
Save the Dunes officials hope the Thorgren basin will become a model for other basins in the Lake Michigan watershed.
