Reservoir restoration and management

Reservoir restoration and management

"A reservoir should not be the end point of a river, but its ecological accumulator."

Why Reservoirs Are Becoming a Priority

A properly managed reservoir allows:

accumulate water during dry periods;

reduce destructive floods;

maintain environmental flow;

replenish groundwater;

restore fish resources;

create new wetland ecosystems;

reduce the impact of climate change.

The main problems of modern reservoirs

siltation;

overgrowth;

water bloom;

accumulation of garbage;

accumulation of heavy metals;

disappearance of spawning grounds;

coastal erosion;

blocking fish migration;

deterioration of water quality;

loss of useful volume.

Main directions of the project

1. Continuous monitoring

Used:

Living Mountain Observatory;

TREE AeroSense;

DREVO River Rover Scout;

satellite data;

automatic buoy stations.

Controlled by:

depths;

water quality;

sludge accumulation rate;

temperature;

oxygen;

nutrient content.

2. Cleaning

Used:

River Rover Clean;

floating suction dredgers;

automatic sorting platforms;

River Cargo Platform.

The following are removed:

garbage;

tree debris;

excess sludge;

scrap metal;

sunken equipment;

hazardous waste.

3. Restoration of ecosystems

Created:

spawning areas;

floating islands;

artificial reefs;

swampy filtration zones;

coastal forests;

areas for waterfowl.

4. Sediment management

Instead of fighting sediments, manage them.

Usage:

sand;

gravel;

snake;

organic material.

Application areas:

land reclamation;

floodplain restoration;

creation of islands;

restoration of swamps;

improvement of agricultural soils (after environmental assessment).

5. Restoration of the coast

Used:

willows;

alder;

reed;

rug;

coconut mats;

living fascines;

wooden structures.

DREVO Reservoir Digital Twin

Each reservoir receives a digital twin.

It displays:

bottom relief;

silt map;

temperature;

oxygen;

currents;

fish;

aquatic vegetation;

dam condition;

forecast of volume changes.

DREVO AI Reservoir

Specialized artificial intelligence module.

He predicts:

siltation rate;

water bloom;

risks of oxygen deficiency;

water quality;

optimal filling and discharge mode;

impact of climate change;

environmental consequences of different management scenarios.

New functions of reservoirs

A modern reservoir must perform not one, but several functions simultaneously:

fresh water supply;

flood protection;

energy generation (if hydroelectric power stations are available);

restoration of fish stocks;

water purification;

maintaining biodiversity;

carbon storage in coastal ecosystems;

scientific testing ground;

recreation and ecotourism.

Integration with the DREVO system

Strategic role

In the systemDREVO Living Mountainsthe reservoir is considered asecological water accumulator, and not just an engineering structure.

It must:

receive clean water from the restored catchment area;

maintain maximum useful volume by reducing siltation;

maintain stable flow into rivers during dry periods;

serve as a refuge for aquatic and near-water species;

be part of a unified system of water resources management from the mountain peaks to the sea.

The main principle

The best reservoir is not the one that is cleaned most often, but the one that silts up less due to a healthy watershed.

That is why in the conceptDREVO Living Mountainsrestoration begins not with the reservoir itself, but withwatersheds, slopes, springs, forests and riversto reduce sediment loads, improve water quality and extend the life of hydraulic structures for many decades.
