This study was carried out in order to participate in the conservation of the biodiversity of aquatic fauna and to develop a strategy for the conservation of fauna and flora in a mining environment. The study area is the Cavally River, precisely within the perimeter of the ITY gold mine in the ZOUAN-HOUNIEN department. Fish were sampled using a set of gillnets. Bathymetric surveys were carried out using an echo sounder. A Niskin bottle and a Van Veen bucket were used to sample the water and sediment respectively, prior to laboratory analysis. The inventory studies identified 76 species of fish, 19 species of amphibians and 10 species of shrimp. Some of these species are of conservation interest and merit special attention according to the IUCN (2023). Hydrological studies have shown the obstruction of the watercourse, the increase in suspended solids, the modification of the hydrological regime and the widening of the watercourse bed. Measurements of heavy metals such as arsenic, mercury and total cyanide showed traces of these metals in the sediments of the watercourse at values above the WHO guide value. In order to limit the loss of fish diversity, aquatic organism transfer activities were carried out. A fry production centre was built to produce species of conservation interest (Coptodon walteri and Micralestes eburneensis) and stock the Cavally river. Secondly, to supply the community with Oreochromis niloticus fry. At the end of each year, hydrobiological, hydrochemical and hydrological monitoring studies are carried out to guide the ITY mining company in its ecological monitoring of the Cavally river. This habitat, deeply disturbed by mining, is a danger for endemic species whose distribution is restricted. These species are of real conservation interest.

High Absoluteness Dtm Editing and Orthophoto speaking of a Producing Area Using Uav Imagery
Bland: This project was executed by SBL for a forming company having operations in Africa. The covered effectually 32 sq.km concerning land falling entree the south western part apropos of Congo.This vision was awarded to SBL based on the excellent quality and profitability shown during an earlier await because Landuse and Landcover mapping. The client requirement was for the creation of hight delicacy DTM edited to 0.2m, DSM of 0.2m and orthophotos of 10cm GSD using UAV imagery. Client: Client is a mining company based in the UK and having mining operations in various parts of African continent. Geography: 32 sq.km apropos of make port falling adit the south western part of Congo. Donkeywork: Mining. Challenges: GCP distribution was not even and as all creation getting a good quality stereo model became difficult. So SBL's experts suggested suitable areas for collecting additional GC useful in the end. Fixing the terrain expanse and natural world body was a challenge identically the vicinity is a dense scatter seed with large swathes of rainy land. Single messages organic being pertaining to 0.2m handling and viewing it was laborious. Editing 0.2m DTM was a very b Approach: SBL used state of the art UAV softwares in carrying out the Aerial Locking on concerning the UAV images. Rear Point cloud densification and DSM hallowed Undistorted images were generated by the UAV software after the tissue concerning DSM law agent reports were imported into Inpho Match AT and pa system models were created in it. After this DTM were generated and edited using Inpho DT Master software. SBL's highly experienced professionals produced grammar school accuracy DTM by the flawless usage of soft and cramping breaklines. Summit manmade structures and vegetated areas were interpolated to terrain mound after plotting breaklines which were orderly in passage to terrain heights. The edited DTM points were exported in XYZ format and bulge twin with dispatched into the client. Benefits: The client benefited round about this work avant-garde<\p>
Getting high accuracy DTM's upon 0.2m by the convention of stone-cold edge UAV softwares. To some extent viable turnaround at once. Use of photogrammetry software along together on UAV software helped in getting a good DTM output.<\p>
