  • Hatfield-1202: Identify rivers, lakes and wet areas to apply safe setback distances

 

 Identify rivers, lakes and wet areas to apply safe setback distances

Challenge ID:

HCP-1202

Originator:

Onshore: Hatfield

Title:

Identify rivers, lakes and wet areas to apply safe setback distances.

Theme:

ON 1.2: Seismic Planning - Identification of adverse terrain for trafficability

Consortium Lead:

RPS Group

Interviewed Company:

RPS Group

Geography:

ON.REG.00 - Generic onshore

Challenge Description

What is not possible / not adequately addressed at present?

Water bodies and wet areas need to be mapped to ensure proper setbacks are applied. Small lakes, rivers and wet areas may be inadequately mapped. It is important to avoid surface water and any potential impact on potable water.

What effect does this challenge have on operations?

Without up to date information, on the fly changes may be required to line design and gaps in source acquisition occur. Sufficient mitigation is more likely with adequate advance knowledge.

Thematic information requirements:

Water quantity

Distribution and status of infrastructure

Topographic information

What do you currently do to address this challenge? 

How is this challenge conventionally addressed?

Topographic maps, aerial photography and other available satellite images. Review historical data to look for seasonal changes. Use LiDAR data where available.

What kind of solutions do you envisage could address this challenge?

Derive water courses based on DEM. Map of water bodies including under forest canopy.

What is your view on the capability of technology to meet this need?

Are you currently using EO tech? If not, why not?

LiDAR survey and high-resolution satellite imagery is expensive. Seasonal variation in water bodies and wet areas requires multi-temporal and wet season imagery.
