LSTM neural lattice learning catchment dynamics
A KAJO research initiative · Map app coming soon

The story behind
every Spanish river.

CAMELS-ES is an open large-sample dataset of Spanish catchments — and the ground truth behind a deep-learning model that simulates daily streamflow anywhere on the peninsula. This page tells the story; the interactive map app will live behind it.

/ Background

Why camels,
why beavers?

CAMELS — Catchment Attributes and Meteorology for Large-sample Studies — is the backbone dataset of modern data-driven hydrology. Versions exist for the US, Chile, Brazil, Australia and the UK. This work introduces one for Spain.

The beavers are the LSTM networks: tireless builders that learn how rainfall, soil and terrain shape rivers, day after day. Together they make every Spanish stream observable — even ungauged ones.

/ The dataset

CAMELS-ES,
a national catchment archive.

Daily forcings and observed streamflow paired with hundreds of static descriptors per catchment — the first large-sample hydrological benchmark for Spain, distributed openly via Zenodo.

Coverage
Peninsular Spain
Time series
Daily meteorology + streamflow
Static attributes
Geomorphology, soil, land use, vegetation
Initiative
Aligned with global CARAVAN

/ The models

Two LSTMs,
one peninsula.

01

National streamflow LSTM

A single recurrent neural network trained on CAMELS-ES that simulates daily streamflow at any point of peninsular Spain — gauged or ungauged.

02

LISFLOOD-OS emulator

A second LSTM trained to reproduce the LISFLOOD-OS hydrological model used by EFAS, with the same forcings, static maps and calibrated parameters as input.

/ Coming next

The interactive map
lives behind this page.

Browse Spanish catchments, inspect simulated streamflow time series and compare CAMELS-ES observations with both LSTM models — directly on the map.
